:02:07. > :02:09.In 2010, Dilma Rousseff became the first woman to be elected
:02:10. > :02:15.In March 2013, just over halfway into her first term in office,
:02:16. > :02:18.she was on a career high, enjoying approval ratings
:02:19. > :02:23.She then narrowly won her second election in October 2014.
:02:24. > :02:27.But following this, her approval ratings plummeted.
:02:28. > :02:30.According to a poll released in April this year, 63%
:02:31. > :02:33.of respondents across the country said her government
:02:34. > :02:40.Experts said this reflected voters' disillusionment with a deep
:02:41. > :02:43.recession and the corruption scandal involving the state-controlled
:02:44. > :02:49.She was then suspended in May this year after the Senate voted to go
:02:50. > :02:57.And for the latest, let's cross live to the BBC's Julia Carneiro
:02:58. > :03:11.Julia, this is not surprising, of course, but it is still pretty
:03:12. > :03:20.shocking. Just how significant is this vote? It is a very dramatic
:03:21. > :03:27.moment here in Brazil. We have been discussing this proceeding is nine
:03:28. > :03:32.months, since it was established by Congress, and now we have had the
:03:33. > :03:37.decisive moment with President Dilma Rousseff stripped of her mandate.
:03:38. > :03:40.This is the second time this has happened since democracy was
:03:41. > :03:44.re-established here in Brazil in 1985 after the military
:03:45. > :03:51.dictatorship. Brazil is still a young democracy after that period,
:03:52. > :03:55.and this is, of course, a moment of gravity. We have seen senators
:03:56. > :04:02.celebrate inside Congress, singing the national anthem, but some
:04:03. > :04:07.senators were also standing still, silent, with lots of gravity in
:04:08. > :04:10.there. This reflects what is felt in the Brazilian population. We have
:04:11. > :04:15.seen many people celebrating today, millions have taken to the streets
:04:16. > :04:18.over past month calling for her impeachment, but there are also many
:04:19. > :04:24.other people who did not agree with the way this was going forward. Is
:04:25. > :04:27.this the end of her career because she did win that second vote that
:04:28. > :04:34.could have barred her from politics for at least eight years? Yes, and
:04:35. > :04:40.this was a surprise. This was a decision made today to separate that
:04:41. > :04:46.decision and vote on whether she should lose her political rights or
:04:47. > :04:50.not, and it turned out that she did manage to retain her political
:04:51. > :04:56.rights. But I think the blow is still the same, having been stripped
:04:57. > :05:00.of her mandate, it is almost a consolation is that she maintains
:05:01. > :05:08.her political rights. She is not someone who had a political career
:05:09. > :05:12.before being chosen as the president's successor. It was not
:05:13. > :05:15.clear what she would do now, if she would still want to pursue the path
:05:16. > :05:20.of the political life, especially after going through this painful
:05:21. > :05:27.impeachment process. But now we are going to see the inauguration of the
:05:28. > :05:36.interim president made official, he used to be the vice president of
:05:37. > :05:39.Dilma Rousseff, and is from the Conservative Party here in Brazil
:05:40. > :05:45.and he is promising to put the economy back on track. That will
:05:46. > :05:49.probably include a series of austerity measures. He has signalled
:05:50. > :05:53.that he will privatise lots of sectors of the economy, that he
:05:54. > :06:00.wants to raise the retirement age. There will be a policy shift now for
:06:01. > :06:03.Brazilians, and it is not clear yet if there will be political stability
:06:04. > :06:06.in this country any time soon. Juliet, with the very latest there
:06:07. > :06:09.in Brazil, thank you. It's one of his most
:06:10. > :06:11.controversial ideas - building a wall along America's
:06:12. > :06:14.southern border to keep Mexicans from illegally crossing
:06:15. > :06:15.into the United States. Now, Donald Trump is expected
:06:16. > :06:18.to arrive shortly in Mexico for a meeting with the country's
:06:19. > :06:20.president, Enrique Pena Nieto. It comes just hours before he's due
:06:21. > :06:23.to make a long-anticipated Some say Trump is softening
:06:24. > :06:32.his stance on the wall. This was his latest statement
:06:33. > :06:34.on the issue. We are also going to
:06:35. > :06:37.secure our border and stop the drugs from pouring in and
:06:38. > :06:42.destroying our country. We are going to build
:06:43. > :06:50.a wall folks, don't worry. In the past, his determination
:06:51. > :06:53.to build a walL, paid for by Mexico, He said it was needed
:06:54. > :07:01.to keep out undesirables. They are bringing drugs in,
:07:02. > :07:04.they are rapists, Not surprisingly, the reaction
:07:05. > :07:08.from Mexico has been The president said Trump's
:07:09. > :07:24.rhetoric is dangerous. There is already a barrier along
:07:25. > :07:27.part of the Mexican border. One former Mexican president said
:07:28. > :07:31.it was ridiculous to force Mexico to pay for an extension
:07:32. > :07:34.right along the frontier. How can any human
:07:35. > :07:42.being think like that? After his meeting in Mexico,
:07:43. > :07:50.Mr Trump will be giving another big With me now to discuss
:07:51. > :08:08.is the BBC's Katty Kay. Of all the things Donald Trump could
:08:09. > :08:13.be doing, and all the places he could be, Mexico would not be top of
:08:14. > :08:17.the agenda, you would think. What is he up to? Well, he likes to surprise
:08:18. > :08:21.people, and this has certainly surprised everybody in the political
:08:22. > :08:25.hierarchy. It has got him a lot of attention, we are talking about it,
:08:26. > :08:30.which is exactly what he likes. It potentially gives him a chance to
:08:31. > :08:33.look statesman-like, look presidential. This is his first
:08:34. > :08:38.meeting with a foreign leader since he announced his bid for the
:08:39. > :08:41.presidency. He could apologise. There is some expectation that he
:08:42. > :08:45.might apologise to the Mexicans for some of the more incendiary things
:08:46. > :08:48.he has said, though not necessarily for his policies, and I guess the
:08:49. > :08:52.campaign is thinking that maybe with Hispanic voters it does not go down
:08:53. > :08:56.too badly, although I suspect it doesn't make too much difference to
:08:57. > :09:02.voters in America. What could possibly be in it for the Mexican
:09:03. > :09:06.president? That is fascinating, why did he invite Donald Trump to visit
:09:07. > :09:12.him? His approval rates are in the 20s, is one of the most unpopular
:09:13. > :09:16.people in Mexico. There will be protests in Mexico City around this
:09:17. > :09:20.visit. What does he get out of being seen with the person that Mexicans
:09:21. > :09:24.love to hate? I'm not sure what is in it for him. He invited both
:09:25. > :09:28.Donald Trump and Hillary Clinton. I suspect he is sitting there wishing
:09:29. > :09:31.he wasn't coming, this is just a headache for him and it does not
:09:32. > :09:36.look great. There is no love lost between the two men they have traded
:09:37. > :09:40.insults on social media. We don't know what they will talk about, do
:09:41. > :09:45.we? Donald Trump has banned the press. The big issues for the
:09:46. > :09:49.Mexicans are the way Donald Trump has spoken about the Mexicans,
:09:50. > :09:53.calling them rapists and criminals who are crossing the border, and of
:09:54. > :09:57.course the wall, which he says Mexicans should pay for. Donald
:09:58. > :10:01.Trump is revising issues around deporting Mexicans who are here
:10:02. > :10:05.illegally, he is fudging that one and we don't know what his policy
:10:06. > :10:09.is, but he is not backing down on that wall, and I can't believe he
:10:10. > :10:12.will go to Mexico City and say that is a mistake after all. We could
:10:13. > :10:13.hear more about that later. Absolutely.
:10:14. > :10:16.Now a look at some of the days other news.

:11:14. > :11:16.that the number of elephants living in the wild in Africa has fallen
:11:17. > :11:19.dramatically over the last decade. That's the finding of a wide-scale
:11:20. > :11:21.census of the creatures, carried out over 600,000
:11:22. > :11:23.square miles of territory, stretching from Mali in West Africa,
:11:24. > :11:26.across to Ethiopia and The survey claims there are around
:11:27. > :11:32.380,000 elephants living on the The numbers of elephants fell
:11:33. > :11:36.by around 30% between 2007 and 2014. In the last two years,
:11:37. > :11:40.that's sped up, with herd sizes Poaching for the ivory
:11:41. > :11:49.trade is the main cause. Looking at individual countries,
:11:50. > :11:53.60% of Tanzania's large herds have And, over the same time frame,
:11:54. > :12:02.the number of elephants in Mozambique has also
:12:03. > :12:05.more than halved. What other way to count
:12:06. > :12:16.a whole continent of For two years, they have been
:12:17. > :12:27.flying just 300 feet Sadly, their findings paint a
:12:28. > :12:44.depressing picture. In country after country, they have
:12:45. > :12:49.countered the carcasses. This is the cost of the poachers
:12:50. > :12:51.and traffickers serving Asia's We have been flying along this
:12:52. > :12:56.flood plain that divides Namibia and Botswana,
:12:57. > :12:58.and all the way along here, we have been seeing
:12:59. > :13:00.carcasses of elephants, some four months old,
:13:01. > :13:17.some less than a week old. Clearly, poaching. The face has been
:13:18. > :13:22.hacked away to get to the tasks. Mike Chase led the research. He
:13:23. > :13:23.found the worst hotspot of poaching are in Tanzania, Mozambique and
:13:24. > :13:26.Angola. Each year we are losing
:13:27. > :13:30.30,000 elephants. If this current rate continues,
:13:31. > :13:33.within nine years Africa could be left with half of the current
:13:34. > :13:35.estimate of African elephants. Botswana has 40% of Africa's
:13:36. > :13:38.elephants, but amid the worst drought in decades,
:13:39. > :13:42.they are under increasing pressure. The only way to protect them
:13:43. > :13:45.is to know how many there are, That means tranquillising some
:13:46. > :13:54.to fit satellite tracking collars. It takes just a few minutes
:13:55. > :14:01.for the drugs to take effect. They have got to be careful

:14:06. > :14:09.given his size, and the collar has to be really big to get that GPS
:14:10. > :14:13.tracker around his neck. They are trying to work as quickly
:14:14. > :14:31.as they can so they can get him The click of the whole process is
:14:32. > :14:33.done, the better. Then, inject the antidote and retreat to a safe

:14:48. > :14:51.the elephants, the dots, used to travel across
:14:52. > :14:53.five countries, but now Elephants clearly have a cognitive
:14:54. > :15:00.ability to understand where they are threatened
:15:01. > :15:03.and where they are safe. In this case, they are seeking
:15:04. > :15:22.refuge and sanctuary in Botswana. Is there room for them? No. Even
:15:23. > :15:26.without a drought, Botswana can't cope with so many elephants. Hunting
:15:27. > :15:31.has been banned here, culling is even being discussed. Currently we
:15:32. > :15:39.are housing a lot of refugee elephants in Botswana. The numbers
:15:40. > :15:44.of elephants in Botswana is so high that it puts a lot of pressure on
:15:45. > :15:48.the environment. The last true century for Africa's elephants is,
:15:49. > :15:53.for the first time, now firmly in the poacher's site. There were days
:15:54. > :15:56.on the great elephant centres when the clay-macro I thought the only
